Preheat oven to 350°.,Grease and flour two 8" round pans.,In a small bowl whisk together flour, soda, and salt.,In a large bowl, cream butter, white sugar and brown sugar until fluffy.,Beat in eggs one at a time.,Mix in bananas*.,Add flour mixture alternately with the buttermilk to the creamed mixture.,Pour into cake pans.,______,While the cake is baking, make frosting: beat butter and cream cheese until smooth, then add powdered sugar and Bourbon- if the amount of booze scares you, add less, or use bourbon flavoring.,*Wefreeze overripe bananas- when it's time to use them, we place them in a cup of hot water for just a few minutes, and they slide right out of their peel.,Once the cakes cool, frost them- the cake (stacked) is pretty heavy and dense, so don't expect a tall fluffy cake.,Stays moist for days if covered properly.
